Definitions

  • the present invention relates to methods of preparing a defatted animal dairy product enriched with microbial anaplerotic oil and animal dairy product rich in odd-chain fatty acids (OCFA) for consumption by human and non-human animals.
  • OCFA odd-chain fatty acids
  • milk fat mainly consists of triglycerides (98%), which are triesters of fatty acids and glycerol. Milk fat is characterized by a large variety of fatty acids and by a large variety of triglycerides which are combinations of these fatty acids. However, most of these fatty acids are even-chain saturated fatty acids. Milk fat and dairy products which are rich in milk fat (such as butter, cream, and cheeses) suffer from a bad nutritional image because of their high saturated fatty acid.
  • Raw milk is also derived from animal sources and contains cholesterol.
  • Nutritional recommendations suggest that cholesterol intake be limited. Consequently, improving the nutritional value of milk fat also involves reducing its cholesterol content.
  • Odd-chain fatty acids are known to have potential health benefits including, but not limited to, reduction of incidence of type 2 diabetes, heart disease, and stroke as well as reducing incidence of neurodegenerative diseases such as Alzheimer's disease and Lou Gehrig's disease.

  • milk is to be interpreted as milk originating from any milk producing mammal, said milk being conventionally used in dairies for the production of dairy products. Accordingly, the term “milk” comprises milk originating from e.g. a cow, a goat, a sheep, a yak, a (water) buffalo, or a camel. Milk from a cow, a goat or a buffalo is preferred.
  • lactose-free means that the lactose content of, for example, an ice cream formulation or a dairy component thereof (e.g., milk or cream) is about 0.5% or less by weight.
  • a lactose-free ice cream formulation may contain no detectable lactose, or may contain lactose at a concentration that is less than about 0.50% by weight (e.g., about 0.45%, 0.40%, 0.35%, 0.30%, 0.25%, 0.20%, 0.19%, 0.18%, 0.17%, 0.16%, 0.15%, 0.14%, 0.13%, 0.12%, 0.11%, 0.10%, 0.09%, 0.08%, 0.07%, 0.06%, 0.05%, 0.04%, 0.03%, 0.02%, or 0.01% by weight, about 0.4% to about 0.5% by weight, about 0.3% to about 0.4% by weight, about 0.2% to about 0.3% by weight, about 0.1% to about 0.2% by weight, up to about 0. 0.

  • the dairy ingredients can contain less than 0.50% lactose by weight (e.g., less than 0.10%, less than 0.05%, or less than 0.01% lactose by weight).
  • Lactose can be detected and/or measured using methods such as, for example, high pressure liquid chromatography (HLPC), or using a blood glucose meter (see, e.g., Metzger, Agriculture Utilization Research Institute, 2013; available at auri.org/research-reports/rapid-measurement- of-the-lactose-content-of-cheese-whey-and-process-cheese-using-a-commercially-available- blood-glucose-meter/) or a LACTOSENS® biosensor (CHR-Hansen; Horsholm, Denmark).

  • microbial anaplerotic oil rich in odd-chain fatty acids refers to an oil containing tridecanoic (C13:0) acid, pentadecanoic (Cl 5:0) acid, heptadecanoic (Cl 7:0) acid, or a combination thereof purified or semi -purified from a microorganism cultured under laboratory or commercial conditions.
  • animal milk refers to milk obtained from a female mammal including, but not limited to, a cow, goat, or ewe.
  • Animal milk is a mixture that consists of 90% water and of various other constituents that can be divided into three categories.
  • the first category known as “lactoserum” (or whey), consists of carbohydrates, soluble proteins, minerals, and water- soluble vitamins.
  • the second category known as the “lipid phase” (or cream), contains fatty materials in the form of an emulsion.
  • the third category known as the “protein phase”, consists of approximately 80% caseins, which form a group of proteins that can be precipitated at pH 4.6 or through the effect of rennet, an enzymatic coagulant, in the presence of calcium.
  • the various caseins form a colloidal micellar complex that can reach diameters on the order of 0.5 pm, with phosphocalcic salts that can be present, for example, in the form of aggregates (“clusters”) of tricalcium phosphate, i.e. Ca9(PO4)e.
  • Such micelles consist of casein subunits made of a hydrophilic layer rich in K-casein surrounding a hydrophobic core, with the phosphocalcic salts being bound to the hydrophilic layer through electrostatic interactions. These phosphocalcic salts may also be present in the internal volume of the micelle, without being bound to the casein.
  • This protein phase also contains soluble proteins, such as lactalbumins and lactoglobulins, as well as albumins and immunoglobulins from blood.
  • Animal milk derived from various mammals will have different amounts of saturated and unsaturated fatty acids. Representative fatty acid profiles of milk produced by goats, sheep, and cows are presented in FIG. 1. In certain aspects, the defatting step removes a portion of these fatty acids.
  • the defatting step removes at least 1%, at least 5%, at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, or at least 99% of at least one saturated fatty acid from the animal milk.
  • the defatting step removes between 1% and 100%, between 5% and 100%, between 10% and 100%, between 20% and 100%, between 30% and 100%, between 40% and 100%, between 50% and 100%, between 60% and 100%, between 70% and 100%, between 80% and 100%, or between 90% and 100% of at least one saturated fatty acid from the animal milk.
  • the at least one fatty acid is tetradecanoic (Cl 4:0) acid. In another aspect, the at least one fatty acid is hexadecenoic (C16:0) acid. In another aspect, the at least one fatty acid is octadecanoic (C18:0) acid.
  • the fluidization step may be performed by adding an aqueous solvent to the raw milk.
  • the aqueous solvent may be a phosphate salt based solution with a concentration lower than 100 mM, the pH of which is between 7.5 and 8.5, preferably between 8.0 and 8.3, such as a 30 mM sodium phosphate solution, pH 8.0, which list is not limiting.
  • Such an aqueous solvent may also contain sodium chloride, the maximum concentration of which is about 40 mM.
  • Such solutions maintain the stabilized micellar structure of the milk (casein micelles in suspension).
  • skimming shall be understood as referring to the separation of the fatty matter of the milk, so as to obtain two fractions, i.e., the skim milk and the cream. Skimming can be performed, for example, using a skimmer or by means of organic solvents such as trichloroacetic acid, which is not limiting. In one embodiment, the skimming of the milk is performed by filtration through a glass fiber support with a positive zeta potential.
  • the Ultipor® GF Plus filter As an example of such a filter, reference may be made to the Ultipor® GF Plus filter as well as to HP series Supradisk filters or AKS active charcoal series (Pall Life Science), GF filters (Whatman), VR Zetaplus filters or Delipid filters (Cuno 3M).
  • the Ultipor® GF Plus filter (Pall) with a 1 pm threshold and the deep filter VR02 or VR04 (Pall) are advantageously used.
  • This filtration step also makes it possible to de-fat the fraction, that is, to remove the lipids, such as the fatty acids, glycerides, and sterols.
  • This defatting can be accomplished via frontal filtration of the milk through the Ultipor® GF Plus filter after having allowed the diluted milk to stand for 30 minutes (such that the fatty matter floats to the surface, thereby optimizing the separation of the cream from the milk).
  • the process of defatting the milk involves centrifugation of the raw animal milk.
  • the raw animal milk is centrifuged at about 1000 x . 1500 x . 2000 x g. 2500 x g. 3000 x g. 3500 x g. 4000 x g. 4500 x g. or 5000 x g.
  • the centrifugation occurs at a cool temperature, for example, at about 1°C to about 15°C, at about 1°C to about 10°C, at about 1°C to about 7.5°C, or at about 1°C to about 5°C. After centrifugation, the animal milk fat is removed from the top of the milk.
  • defatted milk refers to milk having a reduced fat content compared to whole milk.
  • the fat content of the defatted milk is in the range of 0-2 wt %, 0-1 wt %, 0-0.2 wt %, or 0-0.05 wt %, based on total weight of the defatted milk.
  • the defatted milk is skim milk.
  • the present process employs animal milk, which refers to non-human milk, preferably cow's milk.
  • the disclosed process comprises a step of defatting milk to obtain the defatted animal milk.
  • non-defatted animal milk, or just animal milk or whole animal milk is subjected to the defatting step.
  • the defatting step affords the defatted animal milk.
  • the incoming milk prior to or after being defatted, typically after a defatting step, may be subjected to debacterization (bacterial removal), e.g., by UV treatment, heat treatment (e.g., microwave heating, pasteurization, such as HTST, ESL or UHT, or sterilization, for example dry heat or moist heat sterilization) or by bacterial filtration (e.g., microfiltration).
  • debacterization bacterial removal
  • heat treatment e.g., microwave heating, pasteurization, such as HTST, ESL or UHT
  • sterilization for example dry heat or moist heat sterilization
  • bacterial filtration e.g., microfiltration
  • the OCFA-enriched dairy product is prepared by pasteurizing the raw animal milk using, for example, High Temperature Short Time (HTST) or Ultra High Temperature (UHT) pasteurization as described below. Afterwards, the milk goes through a defatting process to standardize the fat content. The raw whole fat milk is defatted to provide skim milk and subsequently the corresponding amount of fat is added to produce 1%, 2% or whole fat milk. This defatting can be done with gravity by either leaving the milk in tanks to settle or though centrifugation (e.g., centrifugation at 5,000-10,000 x g which can help remove bacteria). In some cases, pasteurization comes after standardization of fat content, where the facility needs to cool down the milk before processing it further.
  • HTST High Temperature Short Time
  • UHT Ultra High Temperature
  • additives such as vitamins A and D as well as oils (e.g., microbial anaplerotic oil) can be added to fortify the milk.
  • the oils are added as emulsions and preferably microencapsulated. Examples of methods of microencapsulation are provided below.
  • the milk is then homogenized and packaged ensuring protection from oxygen and light ideally to prevent oils and other labile compounds from degrading.
  • a description of the addition of microbial anaplerotic oil to animal dairy products including 1% and 2% milk is provided in Examples 1 and 2.
  • Pasteurization is used to kill harmful pathogenic bacteria by heating the animal milk for a short time and then immediately cooling it.
  • Types of pasteurized milk include full cream, reduced fat, skim milk, calcium enriched, flavored, and UHT.
  • the standard high temperature short time (HTST) process of 72 °C for 15 seconds completely kills pathogenic bacteria in milk, rendering it safe to drink for up to three weeks if continually refrigerated.
  • a side effect of the heating of pasteurization is that some vitamin and mineral content is lost. Soluble calcium and phosphorus decrease by 5%, thiamin and vitamin B12 by 10%, and vitamin C by 20%. Because losses are small in comparison to the large amount of the two B- vitamins present, milk continues to provide significant amounts of thiamin and vitamin Bl 2.
  • Microfiltration is a process that partially replaces pasteurization and produces milk with fewer microorganisms and longer shelf life without a change in the taste of the milk.
  • cream is separated from the skimmed milk and is pasteurized in the usual way, but the skimmed milk is forced through ceramic microfilters that trap 99.9% of microorganisms in the milk (as compared to 99.999% killing of microorganisms in standard HTST pasteurization).
  • the skimmed milk then is recombined with the pasteurized cream to reconstitute the original milk composition.
  • Ultrafiltration uses finer filters than microfiltration, which allow lactose and water to pass through while retaining fats, calcium and protein.] As with microfiltration, the fat may be removed before filtration and added back in afterwards. Ultrafiltered milk is used in cheesemaking, since it has reduced volume for a given protein content, and is sold directly to consumers as a higher protein, lower sugar content, and creamier alternative to regular milk.
  • the animal milk is homogenized, a treatment that prevents a cream layer from separating out of the milk.
  • the milk is pumped at high pressures through very narrow tubes, breaking up the fat globules through turbulence and cavitation. A greater number of smaller particles possess more total surface area than a smaller number of larger ones, and the original fat globule membranes cannot completely coverthem. Casein micelles are attracted to the newly exposed fat surfaces.
  • the microbial anaplerotic oil is added to the animal milk after homogenization. In another aspect, the microbial anaplerotic oil is added to the animal milk before homogenization. In some aspects, homogenization of the mixture of microbial anaplerotic oil animal milk facilitates the blending of the microbial anaplerotic oil with the milk to form a stable emulsion.
  • the animal milk undergoes Ultra Heat Treatment (UHT), a type of milk processing where all bacteria are destroyed with high heat to extend its shelf life for up to 6 months, as long as the package is not opened.
  • UHT Ultra Heat Treatment
  • Milk is firstly homogenized and then is heated to 138 degrees Celsius for 1-3 seconds. The milk is immediately cooled down and packed into a sterile container. As a result of this treatment, all the pathogenic bacteria within the milk are destroyed, unlike when the milk is just pasteurized.
  • UHT milk does not need to be refrigerated until the package is opened, which makes it easier to ship and store. Demineralization of Animal Milk
  • the disclosed method comprises a demineralization step, wherein the lactose source (e.g., animal milk), or one or more components thereof, is/are demineralized.
  • the lactose source e.g., animal milk
  • Demineralization is particularly preferred for the manufacture of infant formula products, for which it is typically required to lower the mineral content as compared to the incoming milk.
  • Demineralization of the lactose source may be performed by any technique known in the art, such as electrodialysis, ion exchange, salt precipitation, lactose crystallization, membrane filtration techniques such as nanofiltration, optionally enhanced with diafiltration, or combinations thereof.
  • demineralization comprises at least one of salt precipitation, electrodialysis, lactose crystallization and ion exchange, optionally in combination with nanofiltration, more preferably demineralization comprises nanofiltration in combination with at least one of salt precipitation, electrodialysis, lactose crystallization and ion exchange.
  • demineralization comprises at least electrodialysis and/or salt precipitation.
  • demineralization comprises at least nanofiltration in combination with electrodialysis and/or salt precipitation.

  • the animal dairy products provided herein can include, without limitation, lactase, one or more dairy ingredients (e.g., cream and/or milk), egg yolks, sugar, and salt. Flavorings also can be added.
  • the lactase used in the animal dairy products and methods described herein can be a purified and standardized liquid neutral beta-galactosidase. It is noted that the lactase should comply with recommended specification on food grade enzymes. In some cases, the lactase can be Kluyveromyces lactis lactase (EC 3.2.1.23). The lactase can have, for example, a minimum activity of 1900 Neutral Lactase Units (NLU)/g and/or an average activity of about 2100 NLU/g to about 5200 NLU/g (e.g., about 2100 NLU/g).

  • the dairy ingredient(s) can be in liquid form, while in other embodiments, the dairy ingredient(s) can be powdered, evaporated, condensed, etc. Dairy in liquid form can be particularly useful for the addition of lactase, because the lactase reaction can be carried out in the natural suspension of the milk and/or cream. Further, using liquid dairy ingredients can allow the addition of lactase to be done at refrigerated temperatures, typically between about 32° F. and about 41° F. (thus, above freezing), which will not affect the composition of the fat molecules in the dairy ingredient(s) prior to pasteurization. If fat molecules are heated frequently, they may denature, preventing strong agglomeration. Thus, preserving the integrity of fat molecules can be crucial in creating a smooth mixture, since intact fat molecules typically can agglomerate more successfully and solidify the structure of the ice cream during freezing.

  • the process of cheesemaking involves controlling the spoiling of milk into cheese.
  • the milk is traditionally from a cow, goat, sheep or buffalo.
  • the goal is a consistent product with specific characteristics and organoleptic requirements (appearance, aroma, taste, texture).
  • Some cheeses are deliberately left to ferment from naturally airborne spores and bacteria; this approach generally leads to a less consistent product.
  • the raw animal milk is defatted or partially defatted prior to the subsequent steps required for cheesemaking.
  • milk to make cheese, one brings milk (possibly pasteurized) in the cheese vat to a temperature required to promote the growth of the bacteria that feed on lactose and thus ferment the lactose into lactic acid.
  • These bacteria in the milk may be wild, as is the case with unpasteurized milk, added from a culture, frozen or freeze-dried concentrate of starter bacteria.
  • Bacteria which produce only lactic acid during fermentation are homofermentative; those that also produce lactic acid and other compounds such as carbon dioxide, alcohol, aldehydes and ketones are heterofermentative. Fermentation using homofermentative bacteria is important in the production of cheeses such as Cheddar, where a clean, acid flavor is required.
  • the use of heterofermentative bacteria is necessary to produce the compounds that give characteristic fruity flavors and, importantly, the gas that results in the formation of bubbles in the cheese ('eye holes').
  • mold spores fungal spores
  • fungal spores may be added to the milk in the cheese vat or can be added later to the cheese curd.
  • Rennet contains the enzyme chymosin which converts K-casein to para-K-caseinate (the main component of cheese curd, which is a salt of one fragment of the casein) and glycomacropeptide, which is lost in the cheese whey. As the curd is formed, milk fat is trapped in a casein matrix. After adding the rennet, the cheese milk is left to form curds over a period of time.
  • the cheese whey must be released. As with many foods the presence of water and the bacteria in it encourages decomposition. One must, therefore, remove most of the water (whey) from the cheese milk, and hence cheese curd, to make a partial dehydration of the curd. This ensures a product of good quality that will keep.
  • microbial anaplerotic oil is added to cheese curd after draining.
  • Cheddar or other hard cheeses
  • the curd is cut into small cubes and the temperature is raised to approximately 39 °C (102 °F) to 'scald' the curd particles. Syneresis occurs and cheese whey is expressed from the particles.
  • the Cheddar curds and whey are often transferred from the cheese vat to a cooling table which contains screens that allow the whey to drain, but which trap the curd.
  • microbial anaplerotic oil is added to cheese curd after scalding and draining.
  • the curd is cut using long, blunt knives and 'blocked' (stacked, cut and turned) to promote the release of cheese whey in a process known as 'cheddaring'.
  • the acidity of the curd increases and when it has reached the required level, around 0.65%, the curd is milled into ribbon shaped pieces and salt is mixed into it to arrest acid development.
  • the salted green cheese curd is put into cheese molds lined with cheesecloths and pressed overnight to allow the curd particles to bind together.
  • the pressed blocks of cheese are then removed from the cheese molds and are either bound with muslin-like cloth, or waxed or vacuum packed in plastic bags to be stored for maturation. Vacuum packing removes oxygen and prevents mold (fungal) growth during maturation, which depending on the wanted final product may be a desirable characteristic or not. Mold-Ripening

  • milk is first heated, usually to about 85 °C (185 °F), to denature the milk proteins so that they do not form curds. After heating, the milk is allowed to cool to about 45 °C (113 °F).
  • microbial anaplerotic oil is added to the milk after heating and cooling prior to addition of the bacterial culture. The bacterial culture is mixed in, and that temperature of 45 °C is maintained for about 4 to 12 hours to allow fermentation to occur.

  • Butter is a dairy product made from the fat and protein components of milk or cream. Butter is a semi-solid emulsion at room temperature, consisting of approximately 80% butterfat.
  • butter can also be manufactured from the milk of other mammals, including sheep, goats, buffalo, and yaks. It is made by churning milk or cream to separate the fat globules from the buttermilk.
  • the raw animal milk is defatted or partially defatted prior to the subsequent steps required for producing butter. Salt and food colorings are sometimes added to butter. Rendering butter, removing the water and milk solids, produces clarified butter or ghee, which is almost entirely butterfat.
  • Butter is a water-in-oil emulsion resulting from an inversion of the cream, where the milk proteins are the emulsifiers.
  • Unhomogenized milk and cream contain butterfat in microscopic globules. These globules are surrounded by membranes made of phospholipids (fatty acid emulsifiers) and proteins, which prevent the fat in milk from pooling together into a single mass.
  • Butter is produced by agitating cream, which damages these membranes and allows the milk fats to conjoin, separating from the other parts of the cream. Variations in the production method will create butters with different consistencies, mostly due to the butterfat composition in the finished product.
  • Butter contains fat in three separate forms: free butterfat, butterfat crystals, and undamaged fat globules. In the finished product, different proportions of these forms result in different consistencies within the butter; butters with many crystals are harder than butters dominated by free fats.
  • microbial anaplerotic oil is added after churning and draining of the buttermilk. Then the grains are “worked” or pressed and kneaded together. When prepared manually, this is done using wooden boards called scotch hands. This consolidates the butter into a solid mass and breaks up embedded pockets of buttermilk or water into tiny droplets.
  • microbial anaplerotic oil is added after the grains are pressed and kneaded together.
  • butterfat is a mixture of triglyceride, a triester derived from glycerol and three of any of several fatty acid groups.
  • Butter made from a fermented cream is known as cultured butter.
  • the cream naturally sours as bacteria convert milk sugars into lactic acid.
  • the fermentation process produces additional aroma compounds, including diacetyl, which makes for a fuller- flavored and more “buttery” tasting product.
  • Cultured butter is usually made from pasteurized cream whose fermentation is produced by the introduction of Lactococcus and Leuconostoc bacteria.
  • microbial anaplerotic oil is added to cultured butter after pasteurization and/or fermentation.
  • Another method for producing cultured butter is to produce butter from fresh cream and then incorporate bacterial cultures and lactic acid. Using this method, the cultured butter flavor grows as the butter is aged in cold storage. In certain aspects, this method is more efficient because aging the cream used to make butter takes significantly more space than simply storing the finished butter product.
  • a method to make an artificial simulation of cultured butter is to add lactic acid and flavor compounds directly to the fresh-cream butter; while this more efficient process is claimed to simulate the taste of cultured butter, the product produced is not cultured but is instead flavored.
  • Dairy products are often pasteurized during production to kill pathogenic bacteria and other microbes.
  • Butter made from pasteurized fresh cream is called sweet cream butter.
  • Butter made from fresh or cultured unpasteurized cream is called raw cream butter.
  • Cultured butter is sometimes labeled “European-style” butter in the United States.
  • Commercial raw cream butter is rare.
  • butters can be produced. These remain softer at colder temperatures and are therefore easier to use directly out of refrigeration. Some methods modify the makeup of the butter's fat through chemical manipulation of the finished product, some manipulate the cattle's feed, and some incorporate vegetable oil into the butter. “Whipped” butter, another product designed to be more spreadable, is aerated by incorporating nitrogen gas.
  • butter All categories of butter are prepared in both salted and unsalted forms. Either granular salt or a strong brine are added to salted butter during processing. In addition to enhanced flavor, the addition of salt acts as a preservative.
  • the amount of butterfat in the finished product is a vital aspect of production. In the United States, products sold as “butter” must contain at least 80% butterfat. In practice, most American butters contain slightly more than that, averaging around 81% butterfat. European butters generally have a higher ratio — up to 85%.
  • Clarified butter is butter with almost all of its water and milk solids removed, leaving almost-pure butterfat.
  • microbial anaplerotic oil is added after removal of water and milk solids.
  • Clarified butter is made by heating butter to its melting point and then allowing it to cool; after settling, the remaining components separate by density. At the top, whey proteins form a skin, which is removed. The resulting butterfat is then poured off from the mixture of water and casein proteins that settle to the bottom.
  • Ghee is clarified butter that has been heated to around 120 °C (250 °F) after the water is evaporated, turning the milk solids brown. This process flavors the ghee and produces antioxidants that help protect it from rancidity.
  • Cream may be separated (usually by a centrifugal separator) from whey instead of milk, as a byproduct of cheese-making.
  • Whey butter may be made from whey cream.
  • microbial anaplerotic oil is added to whey butter after separating the cream from the whey.
  • Whey cream and butter have a lower fat content and taste more salty, tangy and “cheesy”. They are also less expensive than “sweet” cream and butter.
  • the fat content of whey is low, so 1000 pounds of whey will typically give 3 pounds of butter.
